Our faculty are actively involved in clinical and translational research in a variety of neurological disorders including brain tumors, epilepsy, traumatic brain injury, neurovascular disorders, substance use disorders, fetal and neonatal neurodevelopment and application of AI techniques. Our faculty act as principal investigators or co-investigators on federal and industry funded grants. In addition, we also collaborate with physician teams and imaging scientists within and outside IU on multi-institutional collaborative research projects.
Interim Division Chief
![38670-Radhakrishnan, Rupa]( "38670-Radhakrishnan, Rupa")
Rupa Radhakrishnan, M.D.
Director of Pediatric Neuroradiology
Dr. Radhakrishnan’s NIH and foundational funded research lab focuses on the impact of substance use on the placenta, as well as the maternal, fetal and neonatal brain. She has demonstrated altered rewards networks in infants with prenatal substance exposure. Dr. Radhakrishnan’s research interests also include imaging biomarkers of pediatric epilepsy outcomes, and chronic pediatric neurological diseases.
Department Chair
![64960-Allen, Jason]( "64960-Allen, Jason")
Jason W. Allen, MD, PhD
Chair, Department of Radiology & Imaging Sciences
Dr. Allen’s research lab is funded by a number of NIH, foundation, and institutional grants and uses advanced MR imaging to study traumatic brain injury and cerebrovascular diseases. In his research, Dr. Allen has demonstrated some of the first evidence that post-concussive vestibular impairment may be driven by maladaptive increased weighting of visual sensory input into the vestibular network. His work has also significantly contributed to our understanding of internal carotid artery webs, a frequent cause of ‘cryptogenic’ strokes in younger patients.
